Long enough to wrap around your neck loosely and keep your hands warm at the same time.

Knitting starts at the center of the scarf using a provisional cast on and worked in a thick slip-stitch rib; mitten cuffs are joined for working in the round with a narrower slip-stitch rib over cuffs and palms and a dense cable on the backs. The smaller row gauge of the thermal rib causes the mittens’ hands to slightly flex - nice!
